GAS-BURNER.

Specification of Letters Patent No. 31,472, dated. February 19, 1861.

To all whom it may concern:

Be it known that we, CHARLES MONSON and STILLMAN MOORE, of the city andcounty of New Haven, in the State of Connecticut, have invented a newand useful Improvement in GasBurners, and do hereby declare that thefollowing is a full and exact description of the construction,character, and operation of the same, reference being had to theaccompanying drawings, which make part of this specification, in which-Figure 1 is a perspective view of the burner complete. Fig. 2 is asection of the same showing how the two parts are con nected. Fig. 3 isa perspective view of the same when used with a shade.

Our improvement consists in making the burner of two tubes, one to bepassed over the other, in such manner that we can at will easily changeor bring the flat, or broadside of the flame to any desired position, orgive its fullest light in any desired direction by simply revolving thetip-tube (that is, the tube with the flame to it) turning it by the handconveniently and without danger of producing leakage.

The drawings show tubes slightly conical. e make the inner tubesubstantially as indicated at A Fig. 2, suitable to be screwed on to anypipe in the ordinary way. We make the outer tube substantially as shownat B Figs. 1 and 3 and indicated at B B Fig. 2 with a tip as indicatedat Figs. 1, 2, 8, or of any suitable shape. And we secure this outertube in its place by a screw-pin, so as to prevent it being accidentallyraised (7) Figs. 1, 2, 3) the end of which screw-pin plays in a slightgroove around the inner tube, so that the turning tube, slightlylubricated, may be freely revolved while the screw-pin prevents it beingelevated so as to produce leakage of the burner.

This burner may be used with a shade as indicated in Fig. 3, or withoutit as indicated in Fig. l and with a tip of any kind to give a flatblaze.

The advantages of this improvement consist in that the burner, while theblaze is on, at any time, under any circumstances, may be handily turnedwith thumb and finger, so as to give the largest amount of light at theexact point desired and without risk of leakage.

The glass shade in Fig. 3, is meant to be of oval form, the top edges ofwhich come very near to the flat sides of the flame, and it is found byexperiment to produce a very steady, nonflickering light. This shadeturns with the turning part of the burner.

It is among the advantages of this improved burner that a screen, orreflector, may be attached to the turning part,so as to turn with it,and reflect, or screen, the highest degree of the light at differentpoints as may be desired. A screen thus turning with the turning et mustalways maintain its relative position to the flame.

As regards the construction of this burner, it is not merely the doubletubes which constitute the improvement. \Ve are aware that double tubeshax e been used, with spaces between and openings for air passages &c.(as in the patent of V. V. Bachelder) which however are not designed forturning at will, but, if turned at all, they require the inconvenientturning of a screw, and give room for leakages every time the burner isturned. And we are also aware that there is a common fish-tail burnerhaving what is called a lava tip, a mere bit of porcelainlikecomposition, tapered a little at one end, and setting in a cone-likecavity where it is designed to be fastened by cement. If it should bemerely dropped in, and not cemented, it can be turned when not in use,but while the blaze is on, it is too hot to be touched. \Ve disclaimtherefore the two tubes, or tube and cover, for any such purpose asindicated in the Bachelder patent.

hat we claim as our invention, and desire to secure by Letters Patent,is

The use of the double tubes, (A, and 13,) so as to be readily adjustedin their rotary, without changing their longitudinal position, whenconstructed, arranged, and fitted, as, and for the purpose,substantially, as herein described.
